Abstract

Fluorescent spectra of the mononuclear europium(III) complex, Eu(H2 fsaen) (NO3)·5H2O, and the heteronuclear complexes MEu(fsaen) (NO3nH2O (n = 4 for M = Cu(II) and n = 6 for M = Ni(II)), were compared, where H4 fsaen is a binucleating ligand, N,N′-bis (3-carboxysalicylidene)ethylenediamine. It was found that the fluorescent bands of Eu(III) observed for the mononuclear complex were significantly quenched on forming binuclear complexes.
